[ 1/1 Equation]
Work: Find the solution of equation 710(0.00538-x)(0.0538-x) = 0 .
Question type: Equation
Solution:Original question:
| 710 | ( | 269 50000 | − | x | ) | ( | 269 5000 | − | x | ) | = | 0 |
| Left side of the equation = | 710 | × | 269 50000 | ( | 269 5000 | − | x | ) | − | 710 | x | ( | 269 5000 | − | x | ) |
| = | 19099 5000 | ( | 269 5000 | − | x | ) | − | 710 | x | ( | 269 5000 | − | x | ) |
| = | 19099 5000 | × | 269 5000 | − | 19099 5000 | x | − | 710 | x | ( | 269 5000 | − | x | ) |
| = | 5137631 25000000 | − | 19099 5000 | x | − | 710 | x | ( | 269 5000 | − | x | ) |
| = | 5137631 25000000 | − | 19099 5000 | x | − | 710 | x | × | 269 5000 | + | 710 | x | x |
| = | 5137631 25000000 | − | 19099 5000 | x | − | 19099 500 | x | + | 710 | x | x |
| = | 5137631 25000000 | − | 210089 5000 | x | + | 710 | x | x |
5137631 25000000 | − | 210089 5000 | x | + | 710 | x | x | = | 0 |
After the equation is converted into a general formula, it is converted into:
( 50000x - 269 )( 5000x - 269 )=0
From
50000x - 269 = 0
5000x - 269 = 0
it is concluded that:：
| x1= | 269 50000 |
| x2= | 269 5000 |
There are 2 solution(s).
